Rule for labeling ways not being part of OSM relation in QGIS

A brief overview of what I want to achieve: Create a map showing all cross-country ski trails in a specific region with some customizations/styling on them.

The data come from OpenStreetMap exclusively. Ski trails can be either relations or ways.

I imported the ways and relations from OpenStreetMap using QuickOSM plugin in QGIS 3 with the following Overpass query:

<osm-script output="xml" timeout="25">

    <union>

        <query type="way">

            <has-kv k="piste:type" v="nordic"/>

        </query>

        <query type="relation">

            <has-kv k="piste:type" v="nordic"/>

        </query>

    </union>

    <union>

        <item/>

        <recurse type="down"/>

    </union>

    <print mode="body"/>

</osm-script>

Now I have 2 layers in QGIS, one for lines (OSM ways) and one for multiline strings (OSM relations).

What I want to do is to add a label on ways (showing the value of the attribute piste:name or, if it doesn't exist, name) only if those ways are not part of a relation from the second layer. This is to avoid duplicating the label since these relations already have their name displayed with another labeling rule.

I tried to write rules using geometry functions like contains() but it seems that I can't reference an object from another layer.

Is there a way to achieve what I want to do in QGIS?

Plugin refFunctiond will allow You to interact with geometry from another layer.

From the description:

Plugin that add custom user functions to Qgis Field calculator for referencing, analitically or spatially, between layers, For example retrieving a value from a layer using as a field value or a spatial condition (intersects, disjoint ....) as parameter
